Abstract:

The fender is formed with a plurality of Y-shaped protrusions on the side
facing the wheel. The Y-shaped protrusions are longitudinally arranged in
a row. Each of the Y-shaped protrusions is composed of a vee and a
vertical. The vee opens towards the direction of forward rotation of the
wheel. The water thrown by the wheel will be guided by the verticals of
the Y-shaped protrusions first, and then split by the vee to obliquely
flow out of the fender.

Claims:

1. A fender for a bicycle, the fender having an inside facing a wheel of
the bicycle, the fender comprising: a fixing seat for connecting a rod; a
plurality of Y-shaped protrusions, formed on the inside, longitudinally
arranged in a row, wherein each of the Y-shaped protrusions is composed
of a vee and a vertical bar, and the vee opens towards a direction of
forward rotation of the wheel.

2. The fender of claim 1, wherein each of the Y-shaped protrusions does
not reach edges of the fender.

3. The fender of claim 1, wherein the Y-shaped protrusions are arranged
along an identical central line.

Description:

BACKGROUND OF THE INVENTION

[0001] 1. Technical Field

[0002] The invention relates to bicycles, particularly to fenders used for
bicycles.

[0003] 2. Related Art

[0004] In recent years, cycling is very popular all over the world.
Besides transportation and sport, bicycles have a new purpose, for
pleasure. These three purposes make cycling people constantly increase.

[0005] For the sake of light weight, sports bicycles, such as road bikes
and mountain bikes, do not install fenders. During a competition or
exercise, expectable or unexpectable rain may come down unavoidably. The
rainwater and dirt on the roads will be thrown out onto the cyclists by
the rotating wheels when cycling in a rain. Furthermore, the rainwater
and dirt on the cyclists will flow along the body and down to the
external genitalia and anus. This will invite a potential health problem.

[0006] Even if a bicycle is installed with a fender, a traditional fender
is an arced smooth sheet without any drainage. The water thrown by wheels
will indirectionally scatter after it has been blockaded by the fenders
when moving. The aimlessly scattered water possibly flies onto legs of
the cyclists.

SUMMARY OF THE INVENTION

[0007] An object of the invention is to provide a fender for a bicycle,
which is disposed with drainage protrusions for rapidly and orientedly
guiding out a large amount of rainwater. This can increase the effect of
blocking water of fenders.

[0008] To accomplish the above object, the fender of the invention is
formed with a plurality of Y-shaped protrusions on the side facing the
wheel. The Y-shaped protrusions are longitudinally arranged in a row.
Each of the Y-shaped protrusions is composed of a vee and a vertical. The
vee opens towards the direction of forward rotation of the wheel. The
water thrown by the wheel will be guided by the verticals of the Y-shaped
protrusions first, and then split by the vee to obliquely flow out of the
fender.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] FIG. 1 is a side view showing a bicycle with the fender of the
invention;

[0010] FIG. 2 is a schematic view depicting the fender of the invention
installed on a rear wheel of a bicycle;

[0012]FIG. 4 is a schematic view showing the water flow guided by the
invention.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Please refer to FIG. 1, which is a side view of a bicycle 1 with
the fender 2 of the invention. The fender 2 adopts a light weight design,
i.e. it is about 20-30 centimeters in length and supported by a rod 3
fastened at the wheelshaft. For the sake of light weight, the shortened
length of the fender blockades only the water which would be directly
thrown onto the cyclist.

[0014] FIG. 2 is a schematic view depicting the fender of the invention
installed on a rear wheel of a bicycle. As shown, the fender 2 just
covers a section of a wheel which could throw water to a cyclist, i.e.
the regions A and B in FIG. 2. The fender 2 does perform a specific
effect of water blockading. Region A or B is defined by two tangents to
the wheel at the two points at which two ends of the fender 2 are
located. Region A and B can prevent water from being thrown to the front
and rear of the cyclist, respectively.

[0015] Please refer to FIG. 3. The inside of the fender 2, which is the
side facing the wheel, is formed with a fixing seat 21 for connecting the
rod 3. The inside of the fender 2 is formed with a plurality of Y-shaped
protrusions 22, which are longitudinally arranged in a row along a
central line. Each of the Y-shaped protrusions 22 is composed of a vee
221 and a vertical 222. An opening of the vee 221 is towards the
direction of forward rotation of the wheel. That is to say, all the
Y-shaped protrusions 22 are arranged in the same direction and do not
reach the edges of the fender 2.

[0016] Please refer to FIG. 4. The water attached on a wheel is thrown out
along a tangent to the wheel, and the water still has forward moving
inertia after it has been thrown out. When the fender 2 with Y-shaped
protrusions 22 is installed to a bicycle, the water thrown by the wheel
will impact the inside of the fender 2 first, then be guided by the
vertical bars 222 of the Y-shaped protrusions 22, and finally be split by
the vee 221 to obliquely flow out of the fender 2. As a result, the water
can be rapidly drained out without indirectional splashes.

[0017] While the forgoing is directed to an embodiment of the present
invention, other and further embodiments of the invention may be devised
without departing from the basic scope thereof. As such, the appropriate
scope of the invention is to be determined according to the claims.
